Labor Day is in the rearview mirror, kids are back to school, and a squall of pumpkin spice is upon us. It's that time again to prepare for the equally inevitable respiratory virus season with annual vaccines.

With fervent anti-vaccine activist Robert F. Kennedy Jr. as the country's top health official, it might seem like the rollout of this year's shots could be a disaster. For instance, one of Kennedy's first actions as health secretary last year was to obliterate an ad campaign for flu shots amid a particularly deadly flu season. As we head into this fall, the Centers for Disease Control and Prevention's vaccine advisory committee—which normally sets vaccination recommendations and insurance coverage for the shots—is nonfunctioning. A federal judge ruled in March that the anti-vaccine allies Kennedy installed on the panel were illegally appointed and unfit to serve. All their changes to vaccine policy have been temporarily voided. And meanwhile, Kennedy spent last week trying to obscure the number of babies who died from measles so far this year (it was two, including a newborn).

Big picture

Despite all of that, the fall vaccine effort is looking like it will likely be somewhat smooth, potentially unremarkable even. The Food and Drug Administration has approved updated flu and COVID-19 shots for this season. Those shots have already begun arriving at pharmacies—in case your pharmacy hasn't already sent you multiple texts and reminders. While there are still some snags for access, it seems like it will be a lot like last year's fall vaccine rollout.

Amid a massive Cyclospora outbreak linked to its iceberg lettuce, Taylor Farms is now recalling products containing jalapeños, which were linked last week to a large, multi-state Salmonella outbreak.

On Sunday, August 9, Taylor Farms recalled jalapeño-containing products, including diced jalapeños, dips, salsas, pico de gallo, guacamole, and pre-made salads, burritos, and sandwiches. The foods, which include both branded and unbranded products, were sold across 26 states at major retailers, including Hannaford, Kroger, Target, Trader Joe's, Walmart, and Whole Foods.

The recalled products contain recalled jalapeños from Coast Citrus Distributors, which was linked last week to a Salmonella outbreak that has infected at least 345 people across 27 states, sending at least 36 people to the hospital. No deaths have been reported.

The Food and Drug Administration announced on Wednesday that it's investigating yet another outbreak of Cyclospora, the unicellular foodborne parasite behind a nationwide surge in explosive watery diarrhea illnesses. The FDA said 72 cases have been identified in this outbreak, but the agency provided no details on the situation.

This announcement marks the sixth Cyclospora outbreak investigation the FDA has opened this year. Overall, the Centers for Disease Control and Prevention has gotten reports of more than 11,500 cases (including 4,173 confirmed and over 7,400 probable) from 41 states. Among the cases, there have been 308 hospitalizations and no deaths.

This year's tally so far—just in July—greatly exceeds the normal number of cases the US sees in a whole year. In recent years, the US has reported between 2,000 and 5,000 cases in a year, according to CDC data. With a new outbreak announced, the tally of cases is likely to continue climbing. Nevertheless, when asked about the national surge in cases earlier this week, anti-vaccine Health Secretary Robert F. Kennedy Jr. said the situation was "under control."

Federal officials on Friday announced that shredded iceberg lettuce imported from Mexico and served at Taco Bell restaurants in five states is a source of Cyclospora, the foodborne parasite causing the nationwide surge in cases of explosive, watery diarrhea. The five states are Indiana, Kentucky, Michigan, Ohio, and West Virginia.

A traceback investigation by the Centers for Disease Control and Prevention and the Food and Drug Administration identified a single supplier in Mexico as the source of iceberg lettuce for Taco Bell restaurants where sick people reported eating. While federal authorities did not name the supplier, sources told the Washington Post that it is Taylor Farms.

Taylor Farms was also implicated in a 2024 multi-state E. coli outbreak linked to contaminated onions served at McDonald's and other fast-food restaurants. At the time, FDA inspectors found multiple violations at a Taylor Farms facility in Colorado.

The Trump administration on Monday barred US citizens in the Democratic Republic of the Congo from returning home amid an Ebola outbreak that continues to outpace response efforts.

Reuters first reported late Monday that Americans currently in the DRC or those who have recently traveled to the Ebola-stricken country have been put on a "do-not-board" list. They cannot travel back to the US until they have spent 21 days in a third country. The order, taken under a transportation authority known as Title 49, was independently confirmed by Politico on Tuesday.

Both outlets noted that roughly two dozen Americans who had been set to board flights home on Tuesday have already been blocked by the new rule. It remains unclear if the bar also applies to government workers. The Centers for Disease Control and Prevention has at least two dozen employees working in the DRC.

Independent advisors for the Food and Drug Administration on Friday voted 9–0 in support of approving Moderna's seasonal mRNA flu vaccine, which a Trump appointee at the agency initially tried to block from even being reviewed.

In an all-day meeting, members of the FDA's advisory committee—known as VRBPAC for Vaccines and Related Biological Products Advisory Committee—pored over data and presentations on the vaccine, which is dubbed mRNA-1010 and branded as mFlusiva. The presentations included a review from FDA scientists, which was supportive of the vaccine.

Data from a Phase 3 trial including over 40,000 adults age 50 and older found the mRNA vaccine was around 27 percent more effective against seasonal flu than a standard flu shot. A smaller Phase 3 trial, involving data from nearly 3,000 people age 65 years and older, showed the shot produces stronger immune responses than a high-dose flu vaccine, which is recommended for this age group. The safety profile of the vaccine was also generally good.
